Dr. Heinz Doofenshmirtz (or simply known as Doofenshmirtz), is a 47 year old evil scientist hailing from the fictional German-like country of Drusselstein. He is the head of Doofenshmirtz Evil Incorporated, and he tends not to be evil in the traditional sense, but rather overly dramatic, eccentric and generally clueless. His usual lair is an office building that he apparently owns, though he's worked from other locations when necessary for his plans. He is also the arch nemesis of Perry the Platypus.
Doofenshmirtz, tends not to be evil in the traditional sense, but rather overly dramatic, stupid, eccentric and generally clueless. He is also portrayed as a scientific genius but an utterly, incompetent schemer. He is a self-proclaimed, evil mad scientist who despises almost everything around him, including pelicans, ear hair and such obscure things such as musical instruments starting with the letter "B", and otherwise taking unnecessarily large amounts of effort to accomplish menial tasks, finding the simpler ways to be too much of a bother, as he once tried to take Big Ben instead of just go out and buy a wall clock.
Doofenshmirtz is 6 feet, 2 inches tall and very slender, but he slouches, which causes him to appear shorter. His limbs and fingers are bony and gangly. His legs are usually bent when he stands and walks, and he has a noticeable hunchback. He wears a sleeveless black turtleneck shirt, under a long, thin white lab coat. With that he wears long gray or dark green slacks, and black shoes, and more recently, his shoes seem to have a small heel.
- Doofenshmirtz means "stupid ruler of the home", Doof is the German word for "stupid" or "idiot".
- When a Perry level is completed, Doofenshmirtz may yell out his famous quote, "Curse you, Perry the Platypus!"
